​The biggest gaming market in the list is certainly Japan, a territory where U.S. console manufacturers such as Microsoft have long struggled to gain a foothold against Japanese console makers Nintendo and Sony. Atari, the first major U.S. console manufacturer, faced widespread problems launching its devices in Japan, and Microsoft's Xbox line has gained little traction in the country despite efforts to make games more in line with Japanese culture, such as "Blue Dragon" for the Xbox 360.

While Japan seems like a hard sell for Microsoft's console, the company is seeing strong results from the launch of Respawn Entertainment's first-person shooter "Titanfall" last week. According to Microsoft, last week "saw the highest number of hours logged on Xbox Live since the launch of Xbox One."

Microsoft's blog post promises "much more to share at a local level towards the end of April," possibly referring to local TV service support in each market.
